9 Claims.

This invention relates to phonographs, and more particularly to business phonographs which are primarily adapted and principally used for both recording and reproducing dictation.

Phonographs of this type commonly include a support adapted to bear and rotate a record tablet, and a carriage bearing suitable translating means and capable of motion simultaneously with, but in a direction transverse to that of, the motion of theadjacent record tablet surface. A selective control is provided over the function of the machine, adjustable to at least two positions. In one, the recordation position, it causes engagement with the tablet surface of translating means adapted to produce a record in such surface, upon rotation of the latter, of sound and particularly dictation transmitted into the phonograph. In another, the reproduction position, the control causes engagement with the tablet surface of translating means adapted to produce sound, upon rotation of the surface, in accordance with a record previously made therein. The selective control is usually (though for purposes of the instant invention not indispensably) adjustable to a third or neutral position, wherein it maintains all translating means out of engagement with the tablet surface, irrespective of rotation of the latter.

In order that a person transmitting dictation into the phonograph may not mistakenly dictate with the selective control adjusted to other than the recordation position, there are commonly provided means for producing a sustained signalusually an intermittent, audible onewhen 35 and as the tablet (hereinafter conveniently referred to as the record, irrespective of its surface condition) is rotated under these circumstances. There are also commonly provided means for producing an essentially instantane- 4 ous signal when recordation is in progress and has approached the limit permitted by the record surface or by the available range of motion of the translating means; it being intended thereby to warn the dictator to cease his dictation 45 pending change of the record in use or some other readjustment properly permitting continuance of dictation.

Conventionally these two signalling means are distinct. As contemplated by my invention, 50 however, they are united in a single device with appropriate actuating means. Preferably this device produces a signal of sustained rather than instantaneous nature, not only for indicating lack of control adjustment to the recordation position, but also for indicating the approach of the mentioned permissible limit in recordation. This has the material advantage of obviating failure of perception of the latter indication by the dictator, which frequently occurs in the case of the present instantaneous signal by reason of momentary physical or mental distractions.

Thus it is broadly an object of my invention to provide, in a business phonograph, generally improved means for indicating to the dictator an absence of conditions appropriate to the recordation of his dictation.

It is a further object to provide in such a phonograph a signalling device actuated upon the occurrence of any of a plurality of conditions rendering the phonograph temporarily unsuited for recordation.

It is a still further object to provide in such a phonograph improved means for warning the dictator, both of an adjustment of the selective control to a position other than that for reeordation and or the approach of the recordation process to a permissible limit.

Another object of my invention is the provision of more effective means for warning the dictator during recordation that this process has approached or reached the limit permitted by record surface or available translating means motion.

Other and allied objects will more fully appear from the following description and the appended claims.

In the description reference is had to the accompanying drawings, of which Figure 1 is a top plan view, with portions broken away, of a conventional form of business phonograph in which my invention has been incorporated;

Figure '7 illustrates an embodiment of my invention wherein a visible signalling device is employed, and which is appropriately modified from embodiments illustrated in the earlier figures; and

Figure 8 is a diagrammatic View of an electric circuit appropriate for use with the embodiment of Figure 7.

In the drawings, particularly in Figures 1 and 2, so much of a typical business phonograph is illustrated as is necessary to show the connection of my invention therewith. Thus in these figures there will be seen a mandrel I adapted to carry, and illustrated as carrying, a cylindrical record A. The shaft 2 of the mandrel is journalled in bearing 3, which is secured to the top plate 4 of the phonograph cabinet 8. The mandrel I is adapted to be driven by pulley 5, which through the medium of stud 6 is rotatably mounted on standard I. The pulley 5 is in turn driven through the medium of belt 8 by a motor (not shown) which may be encased in the cabinet 8'.

The continuous rotation of pulley 5 is contemplated; and in order to afford instantaneous control over the rotation of mandrel I there is provided a selectively operable clutch including the coacting members 9 and ID. The member 9 is fastened to pulley 5, while the member ID is splined on the shaft 2. For purposes of description of the instant invention it is sufficient to indicate a clutch control system by its terminal member II-a pivoted arm which engages an annular groove I2 in clutch member I and is adapted to move the latter into and out of engagement with the clutch member 9.

The translating means, which it is not herein necessary specifically to show, are comprised within the unit I4 borne by the carriage I3. The latter is in the form of an arm provided with a boss I near the unit I4 and provided with a bifurcation I6 at its extremity. The boss I5 and bifurcation I6 slidably engage front rod I1 and back rod I8, respectively, and permit motion of the carriage I3 and unit I4 in the longitudinal direction of these rodsi. e., in a direction parallel to the shaft 2 and thus transverse to that of motion of the record surface immediately under the unit I4. The rods I I and I8 are terminally supported by standards I and I, which are secured to the top plate 4 near the left hand and the right hand ends thereof, respectively. During either recordation or reproduction a steady motion of the carriage I3 along the rods, coincident with the rotation of mandrel I, is positively produced by the engagement of the carriage-borne feed nut 20" with a feed screw 20, which screw is geared to the shaft 2 through the screw-borne gear 22 and the shaft-borne gear 2|, and is jcurnalled on bearings 20' in standards 'I and I. This motion is unidirectional and is contemplated as taking place toward standard I; it is hereinafter referred to as the travel of the carriage (or unit) to distinguish it from random or other motion of the carriage effected independently of the feed screw 20.

The selective control for adjustment of the phonograph at least for recordation and reproduction, respectively, and hereinabove mentioned, is shown as lever 25 protruding through slot 26 in the top of carriage I3, immediately above the boss I 5. This lever is shown in Figure l adjusted forwardly of the slot to the recordation (dictate) position. It may however be adjusted to a neutral (off) position by placement intermediately of the slot extremities; or to the reproduction (hear) position by placement rearwardly of the slot.. It is contemplated that each adjustment of the lever 25 causes an appropriate arrangement of translating means with respect to the record and that adjustment of the lever to the neutral position further may disengage the feed nut 20 from the feed screw 2|], thus permitting free motion of the carriage I3 along the rods I1 and I8. The adjustment of the lever 25 may have further functions, certain of which are closely associated with my invention in its illustrated embodiments and are therefore specifically described hereinafter.

The apparatus thus far described is wholly conventional, and forms a typical construction to which appropriate signalling or warning means are desirably applied. Means for signalling adjustment of the control 25 to other than recordation position and means for signalling proximity of the permissible limit in recordation have been illustrated and are described below; it is to be understood that each of such means broadly is well known, but that my invention includes certain novel features in each as herein shown and described, and certain novel interrelations of the two means, which points of novelty are set forth in the appended claims.

In the embodiments of my invention illustrated in the various figures of the accompanying drawings the warning or indicating means is contemplated as including a signalling device proper and an appropriate actuating system therefor. In those embodiments illustrated in Figures 1 through 6 the signalling device is contemplated as a bell B, a hammer 32 adapted to strike the bell, and a resilient arm 3| carrying the hammer. The bell is conveniently carried by a vertical bracket 28 secured to the top plate 4 and occupying a position closely adjacent the face of gear 22. The parts thus far mentioned are most easily seen in Figure 2.

In the embodiments of Figures 1 through 6 the terminal portion of the signal actuating system is an angular trip lever 29 to which the arm 3| is secured. The trip lever may comprise the longer arm 29" and the shorter arm 29', and may be pivoted near the apex of its angle by pivot screw 30 to the vertical face of bracket 28. The trip lever, principally dottedly illustrated in Figure 2, is best seen in Figure 3. Rotation limiting means for the lever 29 is provided in the form of a lug 33 secured to or bent over from the vertical bracket 28 and occupying a horizontal position intercepting the plane of the trip lever; the sides 35 and 34 of a notch 33 formed in the end of the shorter lever arm 29', impinging upon the lug 33, respectively limit the counter-clockwise and clockwise rotation of the lever. In the absence of special forces hereinafter described no particular angular position of the lever 29 is contemplated; it is illustrated in Figure 3, however, in its position of maximum counterclockwise rotation, which for reasons hereinafter appearing may be termed its live position.

It will be seen that with the lever 29 in the described live position, the hammer 32 does not quite touch the surface of bell B. If, however, the lever 29 be rotated slightly in a clockwise direction and then abruptly restored to live position-or in other words trippedthe signalling device will be operated, since the momentum acquired by the hammer before the completion of the abrupt lever return will upon such completion cause the momentary flexing of resilient arm SI and the striking of bell B by the hammer. The device for producing the abrupt return of the lever 29 to live position during tripping is identi- .75

cal with a portion of certain means hereinafter described; it comprises a coil spring 35 rigidly secured at one extremity, intermediately encircling the pivot screw 30, and terminally hooked around the forward edge of the lever arm 29", and urges the lever 29 to counter-clockwise rotation.

The other portions of the signal actuating system operate to trip the lever 29, when this is in its live position, upon each rotation of the feed screw (and hence intermittently throughout rotation of the mandrel 8). These include a member ll, hereinafter referred to as the trip member. This extends essentially tangentially outward from the surface of the feed screw 20; it may be provided with a resilient sleeve portion 40 clamped around the feed screw, and may conveniently be terminally secured to the hub 25 of screw-borne gear 22, as by set screw 23. In order to obviate jamming under the possible circumstance of rotation of the feed screw in a counterclockwise instead of the contemplated clockwise direction (as illustrated in Figures 2 and 3), it is desirable that in tripping the lever 29 the trip member 4! do not engage a portion of, or be rigidly secured to, the lever itself. There has therefore been illustrated, most clearly in Figure 3, a latch 36 pivoted to the trip lever at the intermediate point 271 on the longer arm 29", and extending into the path of the trip member when the trip lever occupies its live position. When the trip member impinges upon the latch from the left, as in clockwise rotation of the feed screw, the latch presents to the trip member a surface secure with respect to the trip lever; this results from the gravity-maintained engagement of the latch edge surface 36 with a lug 38 secured to or bent over from the edge of the trip lever. Thus upon each of its revolutions in the contemplated direction the trip member, first impinging upon the latch, forces the trip lever to rotate slightly in a clockwise direction, and then disengaging the latch, suddenly releases the trip lever; this of course assumes the lever initially in its live position.

The mode of operation of the signal actuating system having been described, attention may be directed to the means for controlling the system to provide operation at the desired times. As

initially mentioned in this specification my invention contemplates the use of the same signalling device for indicating a condition of adjustment of the control 25 to other than recordation position, and a condition of proximity of the per missible limit in recordation. The signal actuating system is therefore so controlled as to operate under each of these conditions. For purposes of description the control means may be separated into three portions: first, means responsive to an adjustment of control 25 to other than recordation position; secondly, means responsive to a condition of proximity of carriage 13 to the permissible limit of its travel; and lastly, means connected with both the preceding means for placing the actuating system in operation upon response of either such preceding means.

As the first of the three mentioned means I employ an arrangement heretofore utilized in signalling lack of adjustment of the selective function control (25) to recordation position. Thus the front rod I1 is mounted to the standards l and 1' in manner permitting its rotation therein. In the bottom of the rod I1 is provided a longitudinal groove or spline ll engaged by a key 25, the key being secured in the hub 25 of the lever 25. Motion of the control lever 25 therefore rotates the rod ll and provides a different angular position thereof for each of the three contemplated control lever adjustments. To the end of rod ll may be secured, as by screw 65, an arm or crank 65, which will be understood to respond to adjustment of control 25 by assuming three respective positions.

As the second of the three mentioned means I employ an arrangement for rotating the rod [8 under appropriate conditions, and an arm or crank 68 secured, as by screw 59, to the end of the rod. In this arrangement the rod I8 is rotatably mounted in the standards I and I, being prevented from executing longitudinal movement as by the key 55 in standard 7 engaging a partial annular groove 56 in the rod.

In considering the means whereby the rod I8 is rotated, it is necessary to observe that Figures 1 through 4 illustrate one modification of such means, and Figures 5 and 6 another. In the first group of figures there is shown secured to the rod 98 near the standard 'l' a split collar 53, as by set screw 54. An urge to counter-clockwise rotation is at all times imparted to the rod l8 (as shown in Figures 2 and 3) by a torsion spring 5'! terminally secured to standard 1 and split collar 53, respectively. Normally this urge is resisted and a definite angular position of rod I8 established by engagement of the key 55 with an extremity of the partial annular groove 56. Depending from the collar 53 is provided a finger 52. This finger lies in the path of a cam surface 5| on the right hand end of a lug 50, secured to the carriage it under its bifurcation l6. Upon engagement of the finger 52 by the cam surface 5i and motion of the surface past the finger, the latter ispushed rearwardly to rotate the rod l8 in a clockwise direction from its original position by an amount which may conveniently be about 25 degrees. In this structure, while the rod I8 is positively moved in the clockwise direction, the torsion spring 57] is relied on to return rod l8 in a counter-clockwise direction to its original angular position upon movement of the carriage disengaging the lug 55 and finger 52. In the modification illustrated in Figures 5 and 6, however, the rod l 8 is positively moved in both directions. Herein a longitudinal groove or spline H is provided along the bottom of rod l8. This groove is provided with an offset of about 25 degrees at a point corresponding longitudinally to the point in the earlier figures occupied by the center of the bifurcation H6 at the time of engagement of cam 5i and finger 52. Projecting from the center of the lower portion of the bifurcation 16 into the groove H is provided a key 10. The engagement of the key with the main portion of the groove maintains the rod IS in a nor- 'mal angular position, and the motion of the key from the main portion through the offset 12 produces clockwise rotation of the rod, the direction of offset being appropriately chosen thereto. Return of the key l0 through the offset to the main portion of the groove of course provides a positive return of rod l8 to its original angular position. It will be understood that either of these two modifications will be arranged to produce the rotation of rod 18 from its normal angular position when the unit M has approached the permissible limit of its travel and that the arrangements inherently maintain the rod in its rotated position until the carriage l3 and unit I4 have been deliberately moved to a more leftward position. The crank 68 will therefore be seen to be responsive by a small clockwise change of position, to a condition of proximity of carriage l3 and unit M to the permissible limit of their travel.

As the third of the three mentioned means I employ the already mentioned spring 35' which urges the trip lever 29 into live position; a rod 60 secured to and extending leftwardly from the arm 29" of the trip lever; and a rod-like member 62 pivoted as at 61 to an extremity of crank 68, having a bifurcation 63 at its opposite extremity engaging a stud 64 secured to the extremity of crank 65, and having a dependent arm 6|. The member 62 and parts associated therewith are so arranged that with the rear rod l8 in approximately the middle of its small range of rotation the member 62 is essentially at right angles to crank 68, whereas with the front rod H in the central of its three positions of adjustment the member 62 is in substantial alignment with the crank 65.

The arm 6| is adapted at times to engage and support the rod 60; these times are those at which the phonograph is in a condition properly permitting continued dictation. The arm 6| then maintains the rod 60 in an elevated position and hence the trip lever arm 29" in a position forward of its live position; under these circumstances the trip lever is in a dormant position, maintaining latch 36 out of the path of the trip member 4|. Thus when crank 68 occupies the most counter-clockwise position in its small rotation range and the crank 65 occupies the most clockwise of its three positions (corresponding to a position of the carriage not close to the permissible limit of its travel and to an adjustment of the control 25 for recordation) the arm 6| will maintain the rod 69 in the mentioned elevated position. These conditions are indicated dottedly in Figure 2.

At other times-those which are appropriate to the operation of the signalling devicethe dependent arm 6| is lowered and withdraws its support of rod 68, whereupon the spring 35 urges the trip lever 29 to its live position. Thus when crank 68 occupies its most clockwise position and crank 65 occupies the most clockwise of its three positions (corresponding to a position. of the carriage close to or at the permissible limit of its travel and to an adjustment of the control 25 for recordation, and as illustrated in Figure 3) the arm 6| will be out of contact with or will just touch rod 69; when crank 68 is at any position within its range and crank 65 occupies the central of its three positions (corresponding to a neutral adjustment of the control 25, and as illustrated in full in Figure 2) the arm 6| will be out of contact with or will just touch rod 60; and when crank 68 is at any position within its range and crank 65 occupies the most counter-clockwise of its three positions (corresponding to an adjustment of the control 25 for reproduction) the arm 6| will be wholly out of contact with the rod 60.

The third of the three mentioned means having been thus described, it. will be apparent that it places the signal actuating system in operation upon the response, as above defined, of either of the first two mentioned means. It will further be apparent that when actuated the signalling device produces an intermittent signal and that it does so only during mandrel rotation-4. e., when the clutch 9|8 is engaged. Slightly modified results are produced in the operation of the embodiment of my invention illustrated in Figures '7 and 8, wherein visible instead of audible signalling means are illustrated.

The general construction shown and described in and in connection with Figures 1 and 2 is assumed in this further embodiment. There are omitted, however, bell B, trip lever 29, trip member 4 and parts immediately associated with and incidental to the operation of these elements; and the member 62 with its arm 6| is replaced by a somewhat different member. The signalling device is shown as lamp 86, which may be mounted on the speaking tube 81 dottedly illustrated in Figure 2 or in any other prominent location. It may be connected by leads 88 to a plug 99, illustrated as a female plug and adapted to connect the leads 88 to the prongs 94 and 94 provided as external contacts on a switch casing 80. Included in the switch casing is a switch 82; this comprises a contact spring 84 connected to prong 94, a second contact spring 83 connected to prong 94', and a contact member 8| adapted to close the switch by impinging upon and electrically connecting the contact springs 83 and 84. The prong 94 and the contact spring 83 may be connected by leads 94" and 85, respectively, across the motor 93 which drives the pulley through the medium of belt 8 (Figure 1). The symbols 90 and 92 respectively designate a source of power for the motor and a switch controlling the motor operation; these are connected in series with the motor. Obviously the closing of switch 92, supplying power to the motor, will also supply power to the circuit 85--83--84-9488- 9494", which may be considered the signal actuating system.

In Figure '7 the switch casing is shown conveniently secured to the standard I. The casing is provided with a boss 79, and within this boss may operate plunger 18 carrying at its lower extremity the contact member 8| already referred to as part of the switch 82. When plunger 18 occupies its raised position as shown in Figure '7, the switch 82 is obviously open; but plunger 18 is adapted to be lowered to close switch 82, and thus forms part of the means for placing the signal actuating system in operation, the balance of which means is described in the following paragraph. As in the case of the embodiments hereinabove described, this means performs its function when either of the cranks 65 and 68 has responded to the conditions intended to be signalled.

Thus to the upper extremity of the plunger 18 may be pivoted, as at 11", a link 11, and the link may in turn be pivoted as at 11' to an intermediate point on the rod-like member 15. At one extremity the member 15 is pivoted to the extremity of crank 68, as by pivot stud 61; at the other extremity it is provided with a bifurcation I00 engaging the stud 64 secured to the extremity of crank 65. The general arrangement of the member 15 with respect to the cranks 65 and 68 is similar to that of the member 62 in previously described embodiments. Its function in cooperation with link 11 and plunger 18 may be most easily described as follows:-

When the crank 68 occupies the most counterclockwise position in its small angular rotation range and the crank 65 occupies the most clockwise of its three positions (corresponding to a condition appropriate for continued recordation and as illustrated in full in Figure '7) the plunger 18 occupies a raised position as shown and the switch 82 is open. If the crank 68 be rotated to the most clockwise position in its range the member 15 will be displaced rearwardly and downwardly,

til

lowering plunger 18 and contact 8| sufiiciently to close switch 82. On the other hand, and independently of the position of crank 68, if the crank 65 be rotated in a counter-clockwise direction to either its central or extreme counter-clockwise positions, the member 15 will swing downwardly about its pivot in a clockwise direction (as illustrated) and will lower plunger 18 and contact 8! at least suificiently to close switch 82.

In previously described embodiments and in this embodiment as thus far described, no differentiation of signal nature in accordance with the condition signalled is effected; the present em.- bodiment as thus far described produces a steady lighting of the lamp 86 as long as the control 25 is adjusted to other than recordation position and produces a similar effect whenever the carriage I3 is close to the permissible limit of its travel. To provide a differentiation of nature between signals respectively indicating these two conditions, I have provided a means for intermittently opening the switch 82 when it would be otherwise maintained steadily closed in response to the second of these conditions. Thus the member 15 is provided, at its point of pivoting to the crank 68, with an elongated slot 95, the arrangement being such that the pivot stud Bl may in the absence of special forces occupy any position between the extremities of the slot. A spring 96, however, is secured to the member 75 as at 11' and to the pivot stud 61, and normally maintains the pivot stud in engagement with the forward extremity of the slot. The member '85 is further provided near its forward extremity with a projection 91 extending downwardly in front of the feed screw 20; the projection 9'! being curved inwardly at 9'! to bring its lower portion within the space between the standards l and l. Suitably secured to the feed screw 20 opposite the projection 91 is provided a cam member 98 having cam portion 98. As long as the crank 68 occupies the most counter-clockwise position in its small angular range the projection 91 lies outside the rotary path of the cam portion 98', no matter which of its three positions is occupied by crank 65. When the crank 68 is moved to its most clockwise position, however, the resulting rearward displacement of the member 15 brings the projection 97 into the path of the cam surface, which upon each of its revolutions will force the projection, and hence the entire member F5, to move forwardly against the force of spring 95 (as is permitted by the slot 95) and the plunger '58 consequently to rise. If the switch 82 has been closed solely by virtue of the clockwise position of crank 68i. e., if crank 65 remains in its most clockwise position, as shown in Figure '7the intermittent rising of the plunger '08 will be of sufiicient degree intermittently to open switch 82, and the signalling device is therefore intermittently rather than steadily actuated. It will be noted that this intermittent actuation occurs only when the carriage is closed to its permissible travel limit during recordation; when the control 25 is otherwise adjusted than for recordation the steady actuation of the signalling device occurs irrespective of the position of the carriage.

I call particular attention to the fact that the signal produced by any of the embodiments of my invention to indicate proximity of the carriage to its permissible limit of travel, is a sustained signal, whether intermittent or steady; and to the fact that it continues until the carriage is deliberately moved in a leftward direction. This has the dual advantages over a momentary Warning signal both of insuring observation of the signal by the dictator, and of warning him of the continuance of conditions inappropriate to recordation if he changes a completed record without returning the carriage to the initial or an intermediate point in its range of travel.

It is to be understood that I do not intend to limit my invention by the specific details illustrated and described for explanatory purposes, but rather intend to express the scope of the invention in the following claims.

In a phonograph having both recording and reproducing functions, including translating means adapted to cooperate with a rotated record, and including record rotating means: the combination of two rods disposed in parallel relation to each other and transversely of the direction of record rotation; a carriage slidably engaging said rods and carrying said translating means; function control means selectively movable to recordation and further positions, said control means being borne by said carriage and engaging a first of said rods to control the angular position thereof; rod-rotating means jointly associated with said carriage and the second of said rods, for controlling the angular position of the latter rod in response to the position of said carriage longitudinally of said rods; a signalling device and means for actuating the same; and means connected with both said rods and influenced by the angular position of each for controlling said actuating means.

9. In a phonograph including translating means adapted to cooperate with a rotated record and including record rotating means: the combination of a rod disposed transversely of the direction of record rotation; a carriage slidably engaging said rod and carrying said translating means; means coacting with said record rotating means for producing unidirectional travel of said carriage along said rod; means normally maintaining said rod in a given angular position; means jointly associated with said carriage and said rod for rotating said rod to a displaced angular position only as said carriage in said travel passes a predetermined point on said rod; and for maintaining said rod in said displaced angular position only while said carriage remains beyond said point; a signalling device and actuating means therefor; and means connected with said rod and influenced by the angular position thereof for controlling said actuating means, to provide actuation of said signal while said rod occupies its displaced angular position.
